i To (all whom it may concernr' Be it known that I, LAURENT FINK-HUGUE- Nor, a citizen of the Republic of France, re-

slding-at Paris, France, have invented certam new and useful Improvements in Processes of Producing Metallic Oxids;'and I do I is illustrated in the accompanying drawings,

. or connection 4, which Figure 1 isa vertical sectional view throu h a suitable form of ap aratus. Fig. 2 is a (fetail vertical sectiona view taken on the line 2 2 of Fig. 1 and showing the metallic oxid or powder receiving chamber rovided with an mcre'asednumber of jet-tu es which supply the reducing-gas, and. Fig. 3 is a detail vertlpral sectional view taken on the line 3 3 of Referring to the drawings by numerals, 1

denotes a receiver or container. for molten metal which is admitted therein'through an inlet-pipe 2, leading from a retort (not shown) and rovided with a controlling valve or cook 3 Said container 1 is closed by a cover in which is provided a suitable pressure-relief valve 6 and a turningplug valve or cook 5.

Screwed or otherwise secured in the upper portion of said container is a discharge nozzle is formed with a cen- 7 and a lower bore or passage 9 of greater iameter or size in cross-section than the said passage 7 and disposed angularly below the same, as shown. These passages or conduits extend entirely through said discharge connection 4, which has formed upon its front or outer end a rejection 11, dlsposed concentrically with t tr'al bore or passa pon its under side intermediate its ends 7 a pro ection 4, in which is formed a bore or conduit 10 passage 10, having its upper end opening into said passa e 9. Steam or other suitable elastic gas or by means of a suitable connection (not shown,) and the fused or molten meta in the container 1 is discharged under pressure, as presently explained, through a pipe e passage 7,

. jected uid is admitted into the passage oror tube 8, which has its upper end communicating with said passage 7 and its lower end opening adjacent to the bottom of said container. The passage 9 has its inner end opening at 9into the interior of the container above the normal level of the molten metal, and its outer end is disposed below the said pro ection 11.

pon the outer end of the discharge nozzle or connection 4 is screwed or otherwise secured a cap 14, preferably in the form of a truncated cone, as shown. The small end of said cone 14 is formedewith a central opening or orifice 15, which alines with said passage 7 Said end of the cone is also formed wit an annular flange 17, upon which is screwed or otherwise secured a cylinder or tube 18 ,which forms a receivin chamber or receptacle for the oxid or pow er, 'as hereinafter explained.

I The outer end of the tube 18 is formed with an opening .19, which is of slight] less diameter than the inner end of said tu e, and projecting radially through said tube adjacent to its inner end is a series of. burner-tubes 20 for a suitable oxidizing-gas. Any number of .these burner-tubes 20 mai be employed. In

Fig. 1 of the drawings have shown two, while in Fig. 2 I have provided a greaternumher and have marked them 20, 20 and 20? but in both instances they are disposed radiall and oppose each other, so as to form a b owpipe.

. Mylimproved process is as follows: The tin or ot or metal to be oxidized is admitted in a state of fusion through the pipe or conduit 2 into the receiver or container 1, and when the latter is sufficiently full the cock 3 is closed.

Steam or other suitable elastic gas or fluid is then admittedinto the passage 10, from which it passes out of the two diverging branches of the passage 9. That portion which passes out of its end 9 enters the container 1 and exerts a strong pressure upon the surface of the molten metal therein tocause the latter to be forced up through the tube 8 and out through the passage 7 into the discharge-nozzle 4. A stream of molten metal is thus prothe truncated cone 14 and at the same time is met bythe jet of steam discharged out of the forwardly-extendin branch of the passage 9. Owing to the disposition of this passage 9 and the shape of the cone 14, a vortex stirring action is set ufp in the latter to cause a thorough mingling o the metal ,and steam, so that as the steam expands the metal will be entirely with great force against the interior ofplulverized. The shock which the metal in sion receives as it strikes the fixed inner surface of the cone also tends to reduce the sauce to powder. The powder thus formed is dis- 5 charged fiom the cone 14 through its outlet? opening 15, and as it passes through the flame o the gas or gases entering through the tubes 20, 20'}, 20*, or 20 said powder is thoroughly om'dized and falls into the race ,tacle 18- in to the form of a metallic oxid. 's metallic om7d may he removed from time, to time through the opening 19 in the outer end of said tube or receptacle.

It will thus he seen that the essential fea- 15 tures ptrny improved process are the mingllisng under strong pressure of a current of ed metal with a current of elastic fluid in order to produce a metallic powder and subjecting this powder to the action of heat, prefzo erably in the form of an oxfidizing-fiame, as

descr bed. I

Having thus described my invention, what 1 claim, and desire to secure by Letters Patcut, is-

The herein-described process of producing z 5 'metallic oxide, which consists in forcing a iused metal to flow in a current under the action of a strong pressure, mingling an elastic fluid with said current, utilizing a portion of the force of the elastic fluid to create said strong pressure, confining the current -to a restricts space to form a vortex jet and finally directing an oxidizing-flame against said jet, essentia y as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
